GAS-REGULATOR.

Specification of Letters Patent No. 13,377, dated August 7, 1855.

To all 'whom t may concern:

Be it known that I, SAMUEL IV. BROWN, of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have in vented a new and useful Gras-Regulator; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, letters, gures, and references thereof.

Of the said drawings, Figure 1 denotes a plan; Fig. 2 a side eleva-tion; Fig. 3 a longitudinal and vertical section at A, B of Fig. l, showing the valve as opened.

The nature of my invention consists in forming a vessel, open at its top, and of any desired shape which is partly filled with liquid packing, and by fitting a movable inverted vessel to the main part, which will easily swing up and down by the pressure of gas, it being guided in such movement by two hinges or points of bearing. Also by the use of a quantity of quick-silver to constitute the regulating valve seat, this quicksilver being brought in Contact with one end of the induction tube, to close it when the regulator is filled, or to open it when the gas in the regulator is nearly exhausted, by operat-ion of the pressure of gas against the inside of the movable top of the regulator.

To enable persons skilled in the art to which my invention appertains, to make, construct, and carry out the same, I will describe it as follows.

I construct a vessel of tin or other suitable substance, the top which is open, as seen at A, A, which is properly supported upon four metallic legs as seen at B, B. To the top of the vessel A, A, I fit an inverted metallic top C, which will freely move up and down in the liquid packing, which occupies a portion of the vessel, as seen at I, this preventing the escape of the gas otherwise than by the burners. The aforesaid top being hinged at one part of it, by which it is guided during its operation, as seen at H.

D is the metallic induction pipe.

E is the metal vessel holding the quicksilver which constitutes the valve seat, and F the quicksilver itself.

Gr is the metal eduction tube leading to the burners.

J is the passage by which quicksilver is deposited in the vessel E, which has to be l done after the several parts of the regulator are adjusted together.

The mode of constructing and adjusting the different parts of my regulators together will readily be understood by any good practical workmen, skilled in this branch of business, by inspection of the accompanying drawings.

It will readily be seen that the objectwhich my improvement is designed to attain is to overcome the sticking which would be caused by the accumulation of gas tar on the two metallic surfaces that would otherwise be necessary to employ to constitute the valve and seat. In some of the gas regulators now in use this serious difficulty is well known to exist as those regulators have to receive a sudden shock ,to disconnect the regulating valve from the seat to which it is fit-ted by reason of the gas tar which accumulates thereon, and causes these surfaces of the valve and seat to adhere together quite firm by the sticky nature of the gas tar, which is well known.

In the operation it will accordingly be seen that my invention will efectually remedy the above diiiculty by the application and use of quicksilver F as seen in the vessel E to constitute the valve seat, while the end of the metal induction pipe D acts as the valve, or vice versa as desired. The pressure of the gas into the regulator and exhausting of the gas by the burners causing the valve seat of quicksilver to rise so as to bring itin contact with the end of the induction tube D to close it and so remain unt-il the top C is depressed far enough to separate the quicksilver from the end of the tube D thereby opening it and allowing a fresh supply of gas to enter, and so on during its operation. It will thus be seen that there is not-hing but the quicksilver for the gas tar to stick to, and as it will not adhere to that, and it being also a dense and perfect liquid the operation and eect is most complete, the top C during the operation vibrating or moving up and down only about one-eighth of an inch at the most.

Having thus explained the construction and use of my gas regulator my claim will be as follows:

I do not claim, expanding a quantity of atmospheric air, and quicksilver by heat, so that the quicksilver and air will expand to close an orifice or tube, after this tube has been regulated by hand to give the amount 10 gas passes 0n its Way to the burners, in combination With the induction tube D, or its mechanical equivalent for the purposes of constituting a self acting valve, or valve seat, to evenly regulate the flow of the gas, essentially in the manner and for the poses fully set forth.
